appears distorted and resembles a trapezoid.
When making the adjustments, set the light source to minimum power.

1. If the image suffers from slight keystone effect, it can be corrected with electronic cropping.
2. If the keystone effect is severe, you can unevenly adjust the feet to compensate for projector
tilt.
It is recommended that you use lens offset to align the center of the image to the center of the
screen before you correct the keystone effect.
